5G’s impact on greenhouse ecosystem

Applying 5G mobile communications technology in a closed environment such as a greenhouse is relatively new. Numerous studies have examined the effects of electromagnetic fields on flora and fauna. Yet, the novel frequencies used by 5G systems are higher than those used by 2G-4G networks. They potentially have a greater impact on smaller organisms, such as plants and pollinators. The aim of this project is therefore to determine whether a 5G network has any effect on the growth of plants or on the behavior of pollinators in a greenhouse.

EMF sensors

Wireless connectivity is key to develop future applications in the greenhouse. At Tomatoworld, a private 5G network enables dedicated 5G greenhouse experiments. Wireless communication in this network takes place through the emissions of electromagnetic fields (EMFs) at a frequency of about 3.8 GHz. We fully want to understand the potential effects of these EMFs on the greenhouse ecosystem. The Smart Sensor Systems research group of The Hague University of Applied Sciences developed specific 5G EMF sensors. These sensors continuously measure the EMF levels at distributed locations and over the course of multiple growing seasons.

Combined data

The measurement data are combined with data on the behaviour of bumblebees. We study this behaviour with a variety of techniques: counters at the bumblebee hive entrances, microphones near flowers and cameras covering large parts of the greenhouse. The third objective of this research is to discover if the plants themselves, as they keep growing, eventually form an obstacle to the transmission of the 5G signal.

Effect of 5G network

Finally, all the data collected on EMF levels, bumblebee behaviour, plant growth and quality of the 5G signal, will be analysed to assess the effect of the 5G network on the growth of plants and the behavior of the pollinators. For a complete picture of the applicability of 5G in a greenhouse, the quality of the 5G signal is assessed at different stages of plant growth, to determine the ideal infrastructure for optimal data transmission. This project combines the in depth expertise of connectivity researchers at The Hague University of Applied Sciences, knowledge on pollinator behaviour experts from Koppert, a leading company in biological crop solutions, and knowhow from crop experts at Tomatoworld.

Three phases

The approach consists of three phases. In the first step, EMF sensors are installed throughout the greenhouse and integrated within the infrastructure. The locations vary in high and low assumed EMF levels. In the second step, three methods for bumblebee behaviour monitoring are developed into sensors: a hive counter using an infrared light, a microphone near tomato flowers to listen to bumblebee buzzes, and a camera to detect bumblebee flight patterns. The third step is to share the results to the scientific community in an open-access journal.

This research is co-financed by the Swiss Research Foundation for Electricity and Mobile Communication (FSM) (project number A2024-05, 2025-2027).

Developing 6G

The global development of 6G is in full swing. This next-generation mobile technology will reach the market in 2030. With the Future Network Services (FNS) programme, the Netherlands is investing in this development. Do IoT Fieldlab has a key role as a partner in this programme. The development of digital technologies is moving fast and many countries and companies worldwide are investing heavily in these areas. The Netherlands is a forerunner in the development of communication technology and intends to take a leading position in the development of 6G as well.

Smart Labour Watch

For many organisations in horticulture, gaining valuable insights into work processes is fundamental to continuous improvement and meeting industry standards. With this goal in mind, Opus Solutions B.V. has developed the OPUS watch, a smart watch specifically for this sector. However, the connectivity required to track activities isn’t always guaranteed in environments dominated by extensive glass and metal structures, such as greenhouses.

Remote robot teaching

Teaching a robot by demonstrating what it should do. Currently, this is quite complicated. In the future, it will bring new opportunities for automation. Engineers from RoboHouse, TNO, TU Delft and Do IoT Fieldlab are analysing different applications, to evolve the remote robot teaching standards.

Humanoids picking tomatoes

The Dutch greenhouse horticulture sector is facing a pressing challenge: while the workload continues to increase, skilled labour is increasingly scarce. There is no shortage of tasks, only of hands to do them. How can we ensure that productivity and sustainability remain safeguarded? The Telegreen project may offer an answer: a collaboration between academia and companies developing an innovative humanoid arm that will support employees and secure the future of the sector.

Insect monitoring in greenhouses

Delft based startup PATS is developing insect monitoring and bio-inspired control systems for greenhouse horticulture. Pest insects in a greenhouse can disturb plant growth or even be a threat to crop yields. Yet, in a healthy ecosystem, some insects can specifically be helpful. Therefore, distinguishing one from the other is preferable, to deploy the appropriate control measure. The aim of this project is to investigate how 5G can contribute to establish fast, reliable connections and improvement in data management.

Listening to plants in the greenhouse

Technological progress in recent years does not yet solve the labour shortage in greenhouse farming. The introduction of 5G is expected to accelerate innovation for sustainable food supply while stimulating more efficient cultivation. For instance, plant health is currently still mainly assessed by the human eye. Delft startup Plense Technologies wants to improve cultivation quality with their ultrasound sensors.
